CC -!- FUNCTION: Muscle contraction.
CC -!- SUBUNIT: Muscle myosin is a hexameric protein that consists of 2 heavy
CC chain subunits (MHC), 2 alkali light chain subunits (MLC) and 2
CC regulatory light chain subunits (MLC-2). Interacts with itr-1 (via c-
CC terminal coiled coil domain). {ECO:0000269|PubMed:12062062}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm, myofibril. Note=Thick filaments of the
CC myofibrils.
CC -!- TISSUE SPECIFICITY: Found exclusively in the pharyngeal muscle.
CC -!- DOMAIN: The rodlike tail sequence is highly repetitive, showing cycles
CC of a 28-residue repeat pattern composed of 4 heptapeptides,
CC characteristic for alpha-helical coiled coils.
CC -!- DOMAIN: Limited proteolysis of myosin heavy chain produces 1 light
CC meromyosin (LMM) and 1 heavy meromyosin (HMM). HMM can be further
CC cleaved into 2 globular subfragments (S1) and 1 rod-shaped subfragment
CC (S2). {ECO:0000305}.
CC -!- MISCELLANEOUS: There are four different myosin heavy chains in
CC C.elegans.
CC -!- SIMILARITY: Belongs to the TRAFAC class myosin-kinesin ATPase
CC superfamily. Myosin family. {ECO:0000305}.
